SAFETY RAZOR.

Application filed November 13, 1924. SerialNo. 749,605.

My invention relates to safety razors and has for its principal objectsa razor in which the angular position of the blade may be easilyadjusted, in which the blade is easily .i removable from and insertablein the blade holder, and which is simple in construction.

The invention consists in the safety razor and in the parts andcombinations of parts hereinafter described and claimed.

In the accompanying drawing which forms part of this specification.

Fig. 1 is a front elevation of a safety razor embodying my invention,

Fig. 2 is a side elevation, the dash lines showing the blade holdingclamp depressed so as to permit removal of a blade,

Fig. 3 is a side elevation similar to Fig. 2, showing the blade in adifferent position from that shown in Fig. 2, and

Fig. 4 is a rear elevation.

A blade holder A is pivotally secured to the end of a suitable handle 1.The blade holder comprises an inclined face 2 constituting a rest orsupport for a razor blade 3, a face 4 that has an offset portion 5frictionally engaging said handle 1 and a curved connecting portion 6.The faces 2 and 4 form a dihedron, being formed with respect to oneanother asa dihedral angle is formed. Preferably a tongue 7 is struck upfrom the blade supporting face 2 and disposed parallel to the bodyportion of the clamping face 4 of the blade holder. A pivot pin 8extends through said tongue 7, said handle 1, and said clamping face 4of the blade holder, whereby the blade holder is capable of rotarymovement. Preferably the clamping face 4 of the blade holder has acurved edge 9 and the offset portion 5 is a segmental area at the middleportion of said face. The handle 1 is preferably flattened on the sides10 adjacent to said tongue 7 and said clamping face 4 of the bladeholder.

Near each side, adjacent to the curved connecting portion 6, theclamping face 4 of the blade holder is provided with a projection 11.lVhen the blade holder is rotated to the limit of its movement in eitherdirection so that the handle 1 extends along the trough formed by thecurved connecting portion 6 of the blade holder, the handle isfrictionally engaged by one of said projections 11 and the blade holderis held in position.

blade holder,

In order to hold the blade 3 in position on the blade rest 2, a clamp 12of more or less U-shape is provided. Said clamp 12 is of spring metaland has a portion 13 that engages the blade 3 near the cutting edgethereof to hold it in position. Said clamp 12 is provided with securingtongues 14 that are disposed in slots 15 provided therefor in the bladesupporting portion 2 of the blade holder and constitute abutments forthe rear edge of the blade. To the rear of the blade 3, the clamp 12 isspaced away from the blade holder, except at its rear edge portion 16where it engages the clamping face 4 of the blade holder and assists inkeeping said clamping face in frictional engagement with the handle.

To the rear of the blade 3, the blade supporting face 2 of the bladeholder is pro- Vided with spaced projections 17. If the clamp isdepressed to the rear of these projections 1?, the front portion of theclamp is swung upwardly, thus releasing the blade and permitting it tobe withdrawn from the blade holder.

The above described razor has numerous advantages. The angular positionof the blade holder may be adjusted so that the blade is in the sameposition as the blade of the ordinary safety razor, it may be adjustedto give the blade an angular position so as to permit a diagonal strokein using the razor, or it may be adjusted so that the blade extendsalong the handle in a position similar to that of the blade of astraight razor. All of these adjustments are easily made without thenecessity for loosening and then tightening securing devices. A. blademay be easily and quickly removed from the holder and a new bladeinserted.

Obviously, numerous changes may be made without departing from theinvention and I do not wish to be limited to the precise constructionshown.

lVhat I claim is 1. A safety razor comprising a handle, a blade holder,said blade holder comprising a blade rest, a clamping face having aportion engaging said handle and a tongue struck up from said blade restand bent against said handle, and a pivot pin passing through saidclampin face, said handle and said tongue.

2. A safety razor comprising a handle. a said blade holder comprising ablade rest, a clamping face having a portion engaging said handle and atongue struck up from said blade rest and bent against said handle, apivot pin passing through said clamping "face. said handle and saidtongue, and a clamp engaging said blade and =aid clamping t ace of saidholder.

3. A safety razor comprising a handle, a blade holder of angularsectionpivotally secured thereto, a clamp of substantially U- section,one end portion of said clamp engaging a blade on said holder and theother end of said clamp engaging said holder, said clamp having tonguesdisposed in slots provided therefor in said holder.

4.. A safety razor comprising a handle, a blade holder ot angularsection pivotallyse cnred thereto, a clamp substantially U- section, oneend portion of said clamp engaging a blade on said holder and the otherend oi said clamp engaging said holder, said clamp having tonguesdisposed in slots provided therefor in said holder, and said holderbeing provided with projections to the rear oi? said blade adapted toengage the clamp when the rear portion is depressed, and cause the frontportion of said clamp to be raised to release the blade.

5. A safety razor nnprising a handle, a blade holder pivotally securedthereto, said blade holder having a clamping face, said clamping facehaving a curved edge portion and provided with an oliset portionfrictionally engaging said handle, a blade on said holder and aresilient clamp engaging said blade and said clamping face of said bladeholder, whereby a single reaction of the clamp presses the offsetportion against said handle and holds the blade.

6. A safety razor comprising a handle, a

and slot connections.

7. A safety razor comprising a handle, a

blade support pivotally secured thereto, said blade support having aclamping 5.100 provided with an offset portion friction-ally engagingsaid handle tor resiliently nolding the support at 'arious positions, ablade and a clamp for holding said blade on said support, and lugs atthe sides ol said clamping :l'ace adapted to engage said handle when theoffset portion of said holder has been swung clear of said handle, thejuncture between the "face and the blade support being adapted topositively limit the consequent swing of the blade support bycooperation with a portion of said handle.

8. A safety razor comprising a blade rest and a clamping taco formedtogether as a dihedron, a handle pivoted inwardly of the dihedron, meanson the said clamping face t'or resiliently engaging the handle forvariably positioning the dihedron over a predetermined range ofpositions, and means within the dihedron for engaging the handle in afixed position when the handle is substantially parallel to the junctureof the dihedral faces and beyond said predeterinined range of movement.
